Water Supply Requirements
Read all directions before you begin.
IMPORTANT:
■ Connect to potable water supply only.
■ If you turn the refrigerator on before the water line is
connected, turn the ice maker off.
■ All installations must meet local plumbing code requirements.
■ Use copper tubing and check for leaks. Install copper tubing
only in areas where the household temperatures will remain
above freezing.
TOOLS NEEDED: Flat-blade screwdriver, 7/16" and 1/2"
open-end wrenches or 2 adjustable wrenches, 1/4" nut driver and
drill bit, cordless drill. Gather the required tools and parts before
starting installation. Read and follow the instructions provided
with any tools listed.
NOTE: Your refrigerator dealer has a kit available with a
1/4" (6.35 mm) saddle-type shutoff valve, a union, and copper
tubing. Before purchasing, make sure a saddle-type valve
complies with your local plumbing codes. Do not use a piercing-
type or 3/16" (4.76 mm) saddle valve which reduces water ow
and clogs more easily.
Water Pressure
A cold water supply with water pressure between
30 and 120 psi (207 and 827 kPa) is required to operate the ice
maker. If you have questions about your water pressure, call a
licensed, qualied plumber.
Reverse Osmosis Water Supply
If a reverse osmosis water ltration system is connected to your
cold water supply, the water pressure to the reverse osmosis
system needs to be a minimum of 40 to 60 psi (276 to 414 kPa).
If the ice maker is still not operating properly:
■ Check to see whether the sediment lter in the reverse
osmosis system is blocked. Replace the lter if necessary.
■ Allow the storage tank on the reverse osmosis system to rell
after heavy usage.
If you have questions about your water pressure, call a licensed,
qualied plumber.
Connect the Water Supply
(on some models)
Read all directions before you begin.
IMPORTANT: If you turn the refrigerator on before the water line
is connected, turn the ice maker off to avoid excessive noise or
damage to the water valve.
Connect the Water Line
1. Unplug refrigerator or disconnect power.
2. Turn off main water supply. Turn on nearest faucet long
enough to clear line of water.
3. Locate a 1/2" to 1¹⁄4" (1.27 cm to 3.18 cm) vertical cold water
pipe near the refrigerator.
IMPORTANT:
■ Make sure that it is a cold water pipe.
■ Horizontal pipe will work. Drill on the top side of the pipe,
not the bottom. This will help keep water away from the
drill and normal sediment from collecting in the valve.
4. Determine the length of copper tubing you will need. Measure
from the connection on lower left rear of refrigerator to the
water pipe. Add 7 ft (2.1 m) to allow for cleaning. Use
1/4" (6.35 mm) O.D. (outside diameter) copper tubing. Be
sure both ends of copper tubing are cut square.
5. Using a cordless drill, drill a 1/4" hole in the cold water pipe
you have selected.
6. Fasten the shutoff valve to the cold water pipe with the pipe
clamp. Be sure the outlet end is solidly in the 1/4" drilled hole
in the water pipe and that the washer is under the pipe clamp.
Tighten the packing nut. Tighten the pipe clamp screws
slowly and evenly so washer makes a watertight seal. Do not
overtighten.
7. Slip the compression sleeve and compression nut on the
copper tubing as shown. Insert the end of the tubing into the
outlet end squarely as far as it will go. Screw compression nut
onto outlet end with adjustable wrench. Do not overtighten.
8. Place the free end of the tubing in a container or sink, and
turn on the main water supply. Flush the tubing until water
is clear. Turn off the shutoff valve on the water pipe. Coil the
copper tubing.
Do not use with water that is microbiologically unsafe or
of unknown quality without adequate disinfection before
or after the system. Systems certified for cyst reduction
may be used on disinfected waters that may contain
filterable cysts.
